EP nurses work in collaboration with electrophysiologists and other healthcare professionals to assist in the management of arrhythmias, conduct diagnostic tests such as electrophysiology studies (EPS), and support patients through procedures like catheter ablation, pacemaker or defibrillator implantation, and other treatments. Post-Procedure Care and Monitoring : Monitor patients closely after an EP procedure, including assessing vital signs, cardiac rhythms, and any signs of complications (e.g., bleeding, infection, arrhythmia recurrence).
